- the traverse mechanism 30 moves in the direction of the disc insertion slot 11 by the second X-axis distance. Therefore, the cam pins 35A and 35B move toward the end of one end of the groove of the fixed cams 34A and 34B by the second X-axis distance, but the other end side (pickup 32 side) of the traverse mechanism 30 has a height of does not change.
- the lift pin 54 moves the groove of the lift cam mechanism 52 by the fourth Y-axis distance, and moves the one end side (spindle motor 31 A side) of the traverse mechanism 30 toward the base body 10 to move the first pin. Place it at the position of the Z-axis distance.
- the disc is separated from the lid 130 and is also separated from the fixing pin 120, so that the disc is in a reproduction / recording state.
- the loading motor is driven and the main slider 40 is moved in the direction of the other end. Basically, the above operation is performed in reverse.
- the disk device of the present embodiment is particularly useful as a disk device in which a display unit, an input unit, an arithmetic processing unit, and the like are integrated, or built in a so-called notebook personal computer body or set integrally. .
